*SPOILERS*The end 'fight' in Portal, finishing before the credits start.See the 'Portal - Credits Song' video in the video responses for the final bit.

Enjoy!

Notes:Yep this was recorded/uploaded quickly after Portal was released. Took 2 hours to finish and I started as soon as Valve unlocked it at 8AM BST. There's immense replayability and unlockables afterwards though, so don't let that hinder your opinion on the game. It's a fantastic, engaging and well executed game.

I deliberately go slower/wait around/play with the eyeballs because the of extra dialogue that's said. I still went faster than i'd have liked though, but that's because of knowing YouTube's size/time restrictions, so apologies for missing out some of the extra dialogue.
